Bug 154262 – sys-apps/coreutils-6.4 - du does not handle -x dirs gracefully

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description gervin23 2006-11-06 09:34:54 UTC]

only affects regular/non-root user. when issuing du on directory with a subdirectory which has the execute bit unset, du gives permission denied and exits. it took me a long time to figure out why this was happening and hunt down which directory it was choking on. would be nice if the app continued to calculate usage and issue a nice informative error message when finished.

package: sys-apps/coreutils-6.4

to reproduce (non-root user):

mkdir testdu
chmod -x testdu
du

[Comment 2 SpanKY 2006-11-06 13:17:16 UTC]

well, not being able to read a -x dir as a non-root user is expected behavior, but du should just issue a warning about that dir and continue on it's way

[Comment 3 SpanKY 2006-11-26 07:21:47 UTC]

upstream has fixed this and released it with coreutils-6.6
